Netapp Vs HP Snaps

Hi all
My company has been looking into buying two new SANs (primary driver is consolidation). We've been looking at VMWare and a pair of DR'd netapp FAS3020 and HP EVA4100's. We have a mix of storage on the floor and this is for our test and development department - we've seen both vendors and both of them are very good at marketing hype (so much so it's starting to put us off...). Can you share your experiences of these two vendors snapshot technology (good and bad)? thanks

SnapRestore allows full volume level recovery. click/ issue a command and your volume is restored to a point in time almost instantly no matter the size 50G or 10Tb.
Without it you can still restore files but you effectively mount the snapshot copy and copy out file by file the ones you want. this works fine for single file restores... not soo good for full volumes. Snaprestore licenses in the scheme of things are pretty cheap and i wouldnt recommend buying a system without it.
I'm not going to say i'm not biased i have been working with netapp technology for 6-7 years but the snap technology is awesome. i had a customer who accidentally left a snapshot on box for 5 months .. no performance impact but it did start taking up some space :) its not uncommon for my customers to hold 4-8 weeks worth of snaps online at any one time, thats quite useful.. try that with an HP ;)

That is true, you are not charged for snapshot technology, but you are charged for snaprestore. Without snaprestore, you can take all the snapshots you want(255), but you can not recovery them.
NetApp is still the best snapshot technology.

Sorry, this is inaccurate. Snap restore is a integral piece of Data OnTap. There are several add-on NetApp products that make managing snapshots easier and safer for the end user, but snapshot recoveries can be done on all NetApp filers.
